Adventures in Switching to Linux

I upgraded to Ubuntu 8.04 tonight but when I did, my mouse didn't work at all anymore! I just had a dead pointer. I was able to get it working previously under Ubuntu 7.10 (Getting my Logitech MX1000 Mouse to Work, Fully, on Ubuntu 7.10) but those settings no longer worked. After playing with the settings some more, removing "CorePointer" from the InputDevice line did it for me. So, I am going to write up a new, improved and simpler how-to for the Logitech MX1000 Mouse on Ubuntu 8.04 Linux (Hardy Heron). This may also work for other multiple button mice but I don't have any other multi button mice to find out.

The very first thing to do is BACKUP your /etc/X11/xorg.conf file. Want a command for that? This will copy it to your home directory as xorg.conf.backup.

cp /etc/X11/xorg.conf ~/xorg.conf.backup

If ever you need to go back to your working config, just login to the terminal failsafe mode and switch the destination and source for the command below (plus add sudo to the front). Like so:

sudo cp ~/xorg.conf.backup /etc/X11/xorg.conf


Now then, first thing to do is install or make sure you have evdev installed. evdev is a generic input driver for keyboards and mice. (Read the man page I linked to for more detailed configuration options. Look most at the Absolute Axis Configuration section.) I think evdev is installed by default but run the line below to install it either way. If it is already installed it will just say so and not change anything.

sudo apt-get install xserver-xorg-input-evdev

Next you will want to edit your xorg.conf file. You must edit it with super privileges or you will not be able to save it. To edit it in gedit, issue this command:

gksu gedit /etc/X11/xorg.conf

Add a new MX1000 InputDevice section and comment out the old mouse InputDevice section. I first thought you didn't have to comment out the old mouse section but if you don't then your buttons will get mapped to 3 and 2 instead of 9 and 8 and they will not work for forward and back.

Section "InputDevice"
Identifier "Logitech MX1000"
Driver  "evdev"
Option  "Name"  "Logitech USB Receiver"
Option  "HWHEELRelativeAxisButtons" "7 6"
EndSection

#Section "InputDevice"
# Identifier "Configured Mouse"
# Driver  "mouse"
# Option  "CorePointer"
# Option  "Device" "/dev/input/mice"
# Option  "Protocol" "ImPS/2"
# Option  "ZAxisMapping" "4 5"
# Option  "Emulate3Buttons" "true"
#EndSection

The "Name" option must match the device name exactly. It is case sensitive. To determine your device name, run:

cat /proc/bus/input/devices

You will get output (along with other devices) that looks something like this:

I: Bus=0003 Vendor=046d Product=c50e Version=2500
N: Name="Logitech USB Receiver"
P: Phys=usb-0000:00:1d.3-2/input0
S: Sysfs=/devices/virtual/input/input5
U: Uniq=
H: Handlers=kbd mouse1 event5
B: EV=7
B: KEY=1f0000 0 100 38 c0000000 c0000 0 0 0
B: REL=103

The Name listed there is the same name that must match in your InputDevice section. Next, add the new Logitech InputDevice that you created in the ServerLayout section and comment out the old mouse. Do it this way so if you messed something up, you can comment out the new Logitech mouse and uncomment the old mouse to switch back.

#    Inputdevice    "Configured Mouse"
Inputdevice    "Logitech MX1000"

Now just logout and log back in. Logging out seems to restart the XServer, a necessary step, but if that doesn't work you can use Ctrl + Alt + Backspace. Use caution as that will kill your X session immediately and all open programs will just get killed.

If you have any problems with this, you might want to try my previous write up from when I was running Ubuntu 7.10. I upgraded from 7.10 -> 8.04 so I may have missed some necessary steps because I'd already done them previously. I don't think I did though.

And for reference, my full /etc/X11/xorg.conf after I was done:

And one more thing, a good program to test out your mouse buttons to figure out what is what is xev. The forward and back buttons should show as 9 and 8. Your left button is 1, right is 3 and pressing the scroll wheel is 2.
